I have PT MP9 (and had a 30 day trial of PT10). I have an MAudio Fastrack Ultra 8R which was automatically detected by PT10 when I started it. I don't know if it's the ASIO drivers
that are installed for the Ultra 8R or if PT10 has what is needed for this device built in.
Does the MBox 2 mini have ASIO drivers?
Avid has a forum. The Windows Pro Tools 10 forum can be accessed HERE
As there are more people familiar with PT10 on that forum, it would be the best place to try and get help.
